Abstract: A wind energy to compressed fluid conversion system has a compressor to compress fluid when the wind energy exceeds a capacity limit of the generator. Instead of trimming blades to create mechanical spillage, excess energy is converted and stored, and can furnish power when the generator experiences a capacity vacancy.

Abstract: A system can include a wind turbine and a generator coupled with the wind turbine for converting wind energy to electrical energy. The system can also include a variable displacement machine configured to use the wind energy to compress a fluid (e.g., when the wind energy exceeds a capacity limit of the generator). The variable displacement machine can also be coupled between the generator and the storage tank and configured to use the compressed fluid to furnish power to the generator (e.g., when the generator experiences a capacity vacancy). The system can also include a storage tank for storing fluid compressed by the variable displacement machine. A variable displacement machine that can be used as a compressor or an expander may include pistons that can be shifted (e.g., to adjust the strokes of the pistons). Further, the variable displacement machine can include a plate with a wobble angle that can be adjusted to be positive, neutral, or negative.
